Carrot and Stick

Rewards and punishments change behaviour, but not always the way you planned.


Carrot and stick is the use of rewards and punishments to motivate behaviour, named after the old way of driving a donkey. It is widely used, but its effectiveness depends on context. Heavy-handed incentives can boost short-term output while causing burnout, resistance or the loss of genuine motivation.

Before using rewards or penalties, ask whether the behaviour is better driven by intrinsic motivation, which crude incentives can undermine. When you use both, make sure they reinforce rather than contradict each other, start with positive reinforcement, and review whether the system is producing the results you want.
